Today Apple released the latest version of their mobile operating system–that is, iOS 4.3–one day earlier than expected. Just about coinciding with the launch of iPad 2, iOS 4.3 brings with it all kinds of goodies including significantly increased Safari performance, iTunes Home Sharing, AirPlay improvements, iPad side switch behaviors, and personal hotspot functionality for iPhone 4; it’s all detailed right here. Bug fixes and the like are bundled in too; hop after the break to find a rundown of what’s included. iOS 4.3 is a free download for all GSM iPhone 4, iPhone 3GS, and third and fourth-gen iPod touch owners. Connect your iOS device to a computer, fire up iTunes, and you’ll be notified to download and install the update.

In related Apple news, their hobby puck has also received a welcome system update. ATV owners will now be able to stream baseball and basketball games through the ether straight to their TVs thanks to MLB.tv and a NBA League Pass Broadband support. These services require pay subscriptions. In addition, Netflix has received 5.1 audio support. Cheers to that!
